D4R II

[Rob Thomson]

Just got two of the new 4 channel rx's from micro technics.

Very nice!

Full telemetry hub; plus a1 for rx built in, and a2 for the likes of way vario!

I am berry happy. Now I can get a vario in my mini dlg gliders

Does it come with the cable that is plugged in to it?

Yes

Ad2
Serial tx
Serial rx

The 4 port cable has a similar plug on the other end.

Guys, if you're using the new frsky receivers and using CPPM and RSSI please read this.. specially if you're flying multirotors or some other kind of flesh eaters..
And this time it is not a joke..

The other recent injury report involved a runaway where the flier tried to reach in and unplug the battery on a quad running full speed. (You do not want to search for the pictures.) The conclusion is to always wear safety glasses and keep a towel at hand to smother the chopper if needed.
I'd also keep the props off when fiddling, as I do with my plane.

You just don't expect that your multi rotor turns itself on when you plug the battery in..

Mines will start being turned upside down on a flat surface when I plug the battery.. the problem is normally when we plug it, is difficult to hold it..

I always test a configuration without props, but mine didn't arm it. Multiwii 2.0.

And I had an other problem with it:
Plugging it the right way it sometimes only outputs 110khz pulses. My multiwii was constant rebooting.
I contacted frsky and after a couple mails they said that I should only use 6 channels for now until they sort it out!

The problem:

I recently got several of the new 4ch RX's as well and wired one up to use with my WS HHigh.
I had to power the HH so I made a mini Y cable to keep the cable clutter and weight down. The HH came pre programmed for Frsky and uses standard servo connectors to get power and output data. I also made a custom adapter to use the viltage divider. I think I'll try and buy some more pigtail cables that fit the mini rx data ports. Any idea of a source? I don't think Frsky sells extra cables or I missed it.
I've not flown all this yet but on the bench everything is working and displaying like my 8ch RX's.
Next is to use the other one as a test for a wireless trainer setup but I put that in hold when I read about the latency issue doing this.
The posting of the trainer mixer that goes in the plane by HK may be a better way to go?
I hope someone will purchase one and report on it soon.
More wires and an extra RX but two of these 4ch RX's are small.

I assume you didn't connect your PPM cable to the RSSI output, did you?

The 6-channel thing is related to the loss of sync problem I reported: viewtopic.php?f=5&t=582&p=7763&hilit=multicopter#p7748

But I've never seen that output you show there... Haven't used my D4RIIs yet though.

At first I did because the docs where wrong at first. But my oscilloscope pointed that one out fast.
And it wouldn't be great to have that signal from the rssi to. Should be a nice squarewave.
I have never seen that output before too.
The rssi gave a nice waveform at the same time by the way.
